It was a gorgeous day at Centre Court, with the sun shining on the athletes standing on the podium, and America's national anthem playing to end the medal ceremony. But then, the flag simply fell from its post.

Olympic staffers were quick to retrieve it. One even carried the flag around with Serena as she, Sharapova, and bronze medalist Victoria Azarenka of Belarus walked to each side of the court to pose for photos.

The flag misadventure comes 10 days after London Olympics officials angered the North Korean delegation by displaying the incorrect flag as their soccer team's players were introduced. The flag they put on the stadium's screen was that of South Korea.
